The present disclosure relates to a blend of waxes for topical application to the skin to provide a soft focus effect and aesthetic benefit, a process for its preparation, and its use in skin care compositions.

There is a need in the market for skin care products that combine beneficial properties such as concealing skin flaws, providing a natural look, providing good aesthetics and providing a desirable sensory feel. While some products now offer hiding power, some look natural, and others offer a desirable sensory feel, there have been repeated challenges to achieve all these attributes in a single product.

There are a wide variety of commercially available cosmetic formulations that enhance the appearance of the skin, but these products generally enhance the appearance by concealing the skin in nature. These products are generally opaque or translucent and deposit a non-transparent layer on the skin to consecrate the skin tone and / or color intrinsically. Products are available that are designed to accurately match a variety of different skin tones, but it is almost impossible to precisely match each individual skin tone. Thus, under certain lighting conditions, especially under natural daylight, the presence of a cosmetic preparation can be prominent, which is undesirable. Moreover, each individual skin has pores and other uneven areas. Preparations designed to conceal the original appearance of the skin by depositing opaque or translucent layers on the skin tend to fill such uneven areas of pores and skin, and this is also especially true after natural light or after several hours of exposure It is visible. In addition, especially in warmer, moister climates, formulations concealing the appearance of the original skin melts and is deposited or "cakeyed" in the uneven areas of the skin (ie pores, wrinkles) Is not preferable. There is a need in the art for a product that keeps the skin looking natural under a variety of lighting conditions.

When the silsesquioxane resin wax is combined with suitable solid particulates, the composition will diffuse the appearance of the skin imperfections while at the same time still allowing the original skin to appear, moisturizing the skin, To provide a unique soft focus effect. The use of silsesquioxane resin wax provides aesthetic benefits and comfort to the skin. The soft focus effect is enhanced by the combination of silsesquioxane resin wax, solid particulate, and other wax. Accordingly, the present disclosure is directed to novel ways of diffusing the appearance of skin defects instead of covering them, such as skin wrinkles, eye wrinkles, signs of endogenous and exogenous skin aging and benign pigment disorders, Or to provide a means of attenuating the appearance of sagging, blackened, fats and / or impure skin, UV-damaged or irritated skin.

The silsesquioxane resin wax (a)

Incorporation of the silsesquioxane resin wax into a cosmetic or skin care preparation significantly increases the soft focus effect.

The silsesquioxane resin wax typically comprises at least 40 mole percent of siloxane units having the general formula (R ₂ R'SiO _1/2 ) _x (R "SiO _3/2 ) _y , where x and y are R 'is a monovalent hydrocarbon having 9 to 40 carbon atoms, R < 1 > is an alkyl group having 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group, R "is a monovalent hydrocarbon group having 1 to 8 carbon atoms or aryl groups.

As used herein, x and y represent the mole fractions of (R ₂ R'SiO _1/2 ) and (R "SiO _3/2 ) siloxy units for each other present in the silsesquioxane resin wax Typically, the value of x ranges from 0.05 to 0.95, or alternatively from 0.2 to 0.8, the value of y ranges from 0.05 to 0.95, or alternatively, the molar fraction of siloxane units may vary from 0.05 to 0.95. The sum of the (R ₂ R'SiO _1/2 ) and (R "SiO _3/2 ) siloxy units present is at least the sum of all siloxy units present in the silsesquioxane resin wax 40 mol%, alternatively 60 mol%, alternatively 90 mol%.

The silsesquioxane resin wax is more siloxy units such as _{^{(i) (R 1 3 SiO}} 1/2) a, (ii) (R 2 2 SiO 2/2) b, (iii) (R 3 SiO 3 / ₂ ) _c , or (iv) (SiO _4/2 ) _d units, which may also be referred to as M, D, T and Q units, respectively. The amount of each unit present in the silsesquioxane resin wax can be expressed as the mole fraction of the total moles of all siloxyl units present in the silsesquioxane resin wax. Thus, the silsesquioxane resin wax may comprise the following units:

_{^{(i) (R 1 3 SiO}} 1/2) a,

(ii) (R ² ₂ SiO _2/2 ) _b ,

(iii) (R ³ SiO _3/2 ) _c ,

(iv) (SiO4 / ₂ ) _d ,

(v) (R ₂ R'SiO _1/2 ) _x and

(vi) (R "SiO _3/2 ) _y .

Wherein R, R ¹ , R ² and R ³ are independently an alkyl group, an aryl group, a carbino group or an amino group having 1 to 8 carbon atoms; R 'is a monovalent hydrocarbon having 9 to 40 carbon atoms; A, b, c and d have a value of from 0 to 0.6; x and y have a value of from 0.05 to 0.95, with the proviso that x + y The value of a + b + c + d + x + y is one.

R 'may be any linear or branched monovalent hydrocarbon having 9 to 40 carbons. Alternatively, R 'is a C18-C40 hydrocarbon group. R "may be a methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, or aryl group.

The ratio of R 'and y / x can be chosen so that the silsesquioxane resin wax has a melting point above 30 < 0 > C.

The solid fine particles (b)

The solid particulates in the composition impart an increased level of light scattering, thereby improving the diffusion or soft focus effect. Particle scattering is a commonly known phenomenon in skin care or cosmetic formulations, but solid particles can often agglomerate in the suspending medium, resulting in undesirable effects of reduced scattering or non-uniform scattering. Even though the particles do not agglomerate in bulk formulations, when the formulation is applied to the skin and the volatile material evaporates, the particles can often agglomerate. This may cause the skin to look uneven / visible or unnatural, or the skin may have visible and visible powder residues. The combination of solid particulate and silsesquioxane resin wax reduces this agglomeration on the skin as well as in the formulation, thereby providing improved scattering effects.

The solid particulate can additionally provide skin with additional effects such as sebum absorption, texture improvement, and texture modification.

Examples of the solid particulate include silica, alumina, mica, clay, titanium dioxide, iron oxide, zinc oxide, boron nitride, zeolite, laponite, talc, silicone resin, silicone elastomer powder, acrylic and acrylate homopolymers and copolymers, Polyethylene, colloidal metal, natural powders such as starch, or any combination thereof. The solid particulates may be any of the above-mentioned examples, such as any processed form of surface treatment for hydrophobing, hydrophilization and / or commercialization.

The solid particulate may have an average particle size of 100 nanometers to 100 micrometers, alternatively from 1 to 50 micrometers, alternatively from 2 to 20 micrometers.

The solid particulate may have any shape, for example, sphere, substantially spherical, hemisphere or irregular shape. The solid particulates may be solid / full, porous or hollow particulates.

In order to achieve the soft focus, the solid particulates are not dissolved and need to be dispersed in the fluid. Particularly effective fluids can simultaneously compatibilize the silsesquioxane resin wax and the additional wax and do not agglomerate the solid particulates, but when waxes and solid particulates are observed using microscopic measurements, Lt; RTI ID = 0.0 > or < / RTI > meters.

Mixing is carried out using conventional mixing means. Heating may be useful to melt the wax before or during mixing.

Soft focus

The term "soft focus" is used interchangeably with the words "blurry" or "fuzzy" in the present invention to describe an optical effect in which an object is viewed by an observer with no apparent resolution. Therefore, cosmetic preparations or skin care preparations that provide a soft focus effect are inherently skin-friendly when applied to the skin, and undesirable features such as wrinkles, pores, pigment spots, etc. are de- It will not be seen with a clear resolution. Thus, the skin appears smoother, younger, more uniform, and still natural to the naked eye.

The soft focus effect is different from the opaque effect or appearance that prevents light from reaching the skin through application of the opaque skin preparation, with all the defects and defects of the skin and the original skin invisible. That is, when an agent that is configured to deliver an opaque effect is applied to the skin, the skin is not visible to the naked eye; Rather, the opaque agent applied to the skin is visible to the naked eye. With soft focus, light still reaches the skin and is emitted again to the observer, but the light is scattered in diffuse, or optical terms, and the skin is inherently visible. Thus, a skin preparation that creates an opaque film on the skin will inherently coat the skin to make the skin appear more uniform, but is often unnatural, while the soft-focus skin preparation according to the present disclosure diffuses light to produce an appearance of skin defects So that the skin is originally visible.

One way to quantitatively evaluate such soft focus effects is through the measurement of light that is transmitted or reflected at a particular angle with respect to light scattered at different angles. The film of the sample material under consideration is first coated on a glass slide using a bar applicator with a fixed gap. The gap distance determines the film thickness. This amount represents the usual amount of skin care agent to be applied to the skin. The film is then dried under ambient conditions to evaporate any volatile content. If the sample material is a solid mixture, the mixture may be first melted and then the molten mixture may be coated on a glass slide. In some cases, the glass applicator can be preheated as well as the glass slide to keep the material in a molten state during the coating process. Alternatively, the solid mixture can first be dispersed in a liquid carrier or made into an emulsion, and thus made into a dispersion or emulsion to be coated.

The glass slide with the coating is then placed in a spectrophotometer, the incident light is illuminated through the sample, and the total transmittance, diffuse transmittance, total reflectance and diffuse reflectance are measured. The instrument is capable of measuring within the wavelength range (approximately 800 to 200 nm) corresponding to the visible and UV regions.

The incident light IL is illuminated through a glass slide GS coated with a sample composition SC. The incident light is partially transmitted, partially reflected, and partially absorbed. Total transmittance (TT) is the transmitted light collected in the front half of the sphere. The diffuse transmittance (DT) is a value obtained by subtracting the light collected within a forward solid angle of 8 degrees in total transmittance. The total reflectance TR is the reflected light collected in the back half of the sphere. The diffuse reflectance (DR) is the total reflectance (DR = TR - SR) minus the light collected at the same reflection angle as the incident angle. Reflected light at an angle equal to the incident angle is referred to as specular reflection (SR). This amount is typically expressed as a percentage of the incident light beam intensity. The amount of absorbed light (AB) is measured at 100% minus the combined total transmittance (TT) and total reflectance (TR). Therefore, AB = 100% - (TT + TR).

In the case of a sample material for characterizing soft focus, the amount of incident light absorbed by the sample material is less than 25%, alternatively less than 10%.

The preferred soft focus effect of the composition according to the present disclosure is that both DT and DR are as large as possible and that most of the light is transmitted instead of being reflected or absorbed. Instead of emitting a large amount of light, when absorbed by the composition, the skin will appear dull or dark, which is undesirable. When most of the incident light is reflected by the composition, the skin looks bright, but since the reflection is from the composition, not from the skin, the skin is not seen in nature. The preferred effect is that the amount absorbed by the composition is minimal and the total reflected amount is relatively small. The greater the fraction of diffused light from light transmitted through the composition or reflected from the composition, the greater the blurry effect, i.e. the skin appears more uniform. In other words, the higher the DT / TT and the DR / TR ratio, the more preferable. A typical optical effect according to the present invention is that the DT / TT is greater than 0.6, alternatively greater than 0.7, the DR / TR is greater than 0.8, alternatively greater than 0.85, the TT / TR is at least 2.5, alternatively at least 5 and the ratio AB / (TT + TR + AB) is 0.25 or less, alternatively 0.1 or less. All of the above measurements are based on measurements on a film having a 37 micrometer thickness made from the composition. Different film thicknesses may yield different measurements for said parameter; For example, you should understand that the thicker the film, the smaller the TT and the larger the AB. Those skilled in the art can adjust the above criteria appropriately to achieve a desired soft focus effect.

The soft focus effect is achieved by a composition comprising (a) a silsesquioxane resin wax, (b) at least one solid particulate having an average particle size of greater than 1 micrometer, and (c) at least one additional wax, To the skin.

Compositions prepared in accordance with embodiments herein can be used in a variety of personal care, cosmetic, and medical applications. The composition, anhydrous composition or emulsion composition may be selected from a lotion, a cream, a moisturizer, a facial treatment, a primer, a concealer, a collector, a pencil, a foundation, a make-up product, a blush, a lipstick, a lip balm, an eyeliner, Lt; RTI ID = 0.0 > cosmetics. ≪ / RTI >
